The sum that decides whether panels pay for themselves in Amsterdam changes on 1 January 2027, when the netting scheme every payback calculation has rested on is withdrawn.
That does not make solar a bad idea, but it does mean a payback figure copied from an older brochure is now wrong.
Solar installers to start with
This is a thin field, and worth saying so: take out the builders’ merchants, the electronics chains, the wholesalers, the energy suppliers and one trade association, and most of what is left are small firms whose review counts run to a couple of dozen.
So these six are chosen for what they actually fit – panels alone, panels with a battery, panels on a sedum roof, panels on a commercial roof, and servicing an array already up there – rather than by a star average resting on a dozen opinions.
Solar Sedum
Solar Sedum puts panels and a sedum roof in under one contract, which is the only place in the city those two trades arrive together, and it has more than twenty years behind it.
Weekday hours of nine to half past five from Wenckebachweg in Overamstel, on 47 reviews at 4.8 with 94 per cent five-star.
Zonnefabriek
Yield is the argument Zonnefabriek makes rather than price, and it puts a consultation and a calculation of expected output in front of any quote.
From Daniel Goedkoopstraat in Overamstel it works nine to six on weekdays, and 113 reviews put it at 4.4.
VerduurzaamNu
VerduurzaamNu sells the complete retrofit rather than panels on their own, pitched at bringing the energy bill down as a single job.
The window for reaching it is the narrowest here, ten to four on weekdays and shut at the weekend, and 67 reviews at 4.9 with 96 per cent five-star are the strongest record in the field.
Voltera
Panels, a home battery, a heat pump and air conditioning can all come from Voltera on one visit, which is the useful shape if the roof is only part of what you are changing.
It opens on Saturdays as well, ten to five, quotes a warranty running to twenty-five years, and works from Keurenplein in Nieuw-West on 16 reviews at 4.5.
C-DEVICE
Servicing an existing system, not only fitting a new one, is on C-DEVICE’s list, which is worth knowing once panels have been on a roof for a few years and nobody has looked at them since.
It works weekdays nine to five from Laarderhoogtweg in Zuidoost, runs a computer consultancy alongside the solar side, and holds 38 reviews at 4.6.
FutureGreen Solutions
Light-weight panels are FutureGreen’s specific answer to a roof that will not carry a conventional array, and the rest of what it offers – battery storage, charging points, energy management – is aimed at business premises rather than houses.
Two reviews is no record at all, so judge it on the stated work and its claim of lifting self-generated use to 80 per cent; the office is by the Olympic Stadium, half past eight to half past five on weekdays.
What changes in 2027
Until the end of 2026 the salderingsregeling lets you net every kilowatt-hour you export against one you import, so exported power is worth exactly what bought power costs.
From 1 January 2027 that stops and exported power earns a feed-in payment instead, set in law at no less than half the supplier’s base tariff.
The practical effect is that electricity used while the panels are producing becomes worth considerably more than electricity sold, which shifts the case toward an array sized to the household rather than to the roof.
Before you take a quote
Have the roof assessed first, because lifting an array off and refitting it to replace a worn covering costs more than doing the roof in the first place.
In an apartment building the roof is shared, so the owners’ association has to agree before anything is fixed to it.
Panels visible from the street on a listed building or inside the protected townscape need permission, and the installer should be raising that, not you.
Reading the offerte
Ask for the panel and inverter make and model, the expected annual yield in kilowatt-hours and the mounting system, so that two quotes can genuinely be compared.
Check the two warranties separately: panels normally carry a long performance guarantee while the inverter’s is much shorter, and the inverter is the part that fails first.
Ask in writing who to ring if output drops after the installation year.
After switch-on
Most systems come with monitoring, and the useful habit is a glance at a sunny-day peak once a month rather than a daily watch.
Panels need almost nothing in Dutch rain, though it is worth checking once a year for new shade from a grown tree or a neighbour’s dormer.
Tell your energy supplier the system is live and check how the meter registers export, because that reading is what the bill will be built from once netting ends.
